Enum JsonTreeProcessError 

pub enum JsonTreeProcessError<R, Q, E>
where
    Q: Copy + Debug,
{
    Budget(MeasuredBudgetError<R, Q>),
    Visitor(E),
}

Identifies whether JSON tree processing failed in infrastructure or domain code.

This enum intentionally remains exhaustive so callers can distinguish the complete set of processing failure domains at compile time. Adding a domain requires a breaking release rather than a #[non_exhaustive] change.

Type Parameters

• R - Resource identity attached to budget failures.
• Q - Quantity representation attached to budget failures.
• E - Error type returned by the visitor.

Examples

use qubit_json::value::traverse::JsonTreeProcessError;

let error: JsonTreeProcessError<(), usize, &str> =
    JsonTreeProcessError::Visitor("visitor rejected the node");
assert!(matches!(error, JsonTreeProcessError::Visitor(_)));

Variants

Budget(MeasuredBudgetError<R, Q>)

A JSON resource measurement or budget rejected a tree node.

Tuple Fields

0: MeasuredBudgetError<R, Q>

Resource measurement that exceeded the configured limit.

Visitor(E)

The caller-defined visitor rejected a budget-admitted node.

Tuple Fields

0: E

Domain error returned by the visitor callback.

Trait Implementations

impl<R: Debug, Q, E: Debug> Debug for JsonTreeProcessError<R, Q, E>

where Q: Copy + Debug + Debug,

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<R, Q, E> Display for JsonTreeProcessError<R, Q, E>

where Q: Copy + Debug, MeasuredBudgetError<R, Q>: Display,

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<R, Q, E> Error for JsonTreeProcessError<R, Q, E>

where Q: Copy + Debug, MeasuredBudgetError<R, Q>: Error, Self: Debug + Display,

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl<R, Q, E> From<MeasuredBudgetError<R, Q>> for JsonTreeProcessError<R, Q, E>

where Q: Copy + Debug,

fn from(source: MeasuredBudgetError<R, Q>) -> Self

Converts to this type from the input type.
